In cellular communication, placement of evolved node base station (eNB) is an important issue. It determines the cost to construct, capacity, coverage ratio and quality of service (QoS). In 2G and 3G standards, eNBs have similar coverage range. The idea of heterogeneous network (HetNet) is launched in long term evolution-advanced (LTE-A), where the network contains different eNBs of different coverage ranges. The HetNet contains both large power macro-cells and less power small-cells such as pico, femto and relay nodes. But the placement of different eNBs is very difficult. We have proposed a four phase scheme for the placement of different eNBs based on uniform clustering concepts. Our placement scheme chooses optimal eNB sites from the candidate sites in the service area. Also according to the constraint of power on each eNB, it will alter the range of cell to offer the proper coverage while satisfying the demands of user. From the simulation outcomes, it is proved that our suggested scheme reduces the system cost and also provides better coverage ratio under the power constraints. © 2017 IEEE.

An uniform clustering based coverage and cost effective placement of serving nodes for 5G

2017 International Conference on Innovations in Electrical, Electronics, Instrumentation and Media Technology (ICEEIMT)

The densification of serving nodes is one of the potential solutions to maximize the spectral efficiency per unit area. This is preposterous on account of conventional base stations (BS) for which site procurement is costly. Long term evolution-advanced (LTE-A) defines the idea of heterogeneous networks (HetNets), where BSs with different coverage and capacity are utilized to guarantee the quality of service (QoS) requirements of the clients. To maximize the transmission quality of the clients in the coverage holes, LTE-A also defines multihop relay (MHR) networks, where the relay stations (RSs) are also placed along with the BSs. Unfortunately, the placement approaches for HetNet and MHR serving nodes are not standardized. In this work, two different approaches like site selection with maximum service coverage (SSMSC) and site selection with minimum placement cost (SSMPC) are proposed, which identifies the required number of serving nodes, their types, and the placement locations to maximize the coverage and to maintain the placement cost (PC) within the limits of the total placement budget. The simulation results demonstrate that the proposed approaches are computationally less complex and offer enhanced performance in terms of aggregate PC, coverage, and power proportion compared to the other conventional approaches.

Fuzzy Logic Based Coverage and Cost Effective Placement of Serving Nodes for 4G and Beyond Cellular Networks

The network capacity has to be maximized to support the ever-increasing data traffic demand. One of thepotential outcomes to enhance the network capacity is to enhance the spectral efficiency per unit area by expandingthe serving node densities. This is unreasonable on account of present Macro evolved node B (eNB) for which siteacquisition is expensive. The idea of heterogeneous network (HetNet) and multi-hop relay (MHR) are extremely prominentin long-term evolution (LTE) standard, where small cells are deployed along with Macro cell. Small cells aremore suitable solution for the coverage and traffic issues experienced by Macro cell users. Unfortunately, HetNetdeployment is not specified in any of the standards. The network operators have been managing tremendous investmentsfor cellular infrastructures. Because of the high cost and lack of radio resources, a precise and productive HetNetdeployment seems uttermost important. In this work, a flexible four-stage fuzzy logic-based HetNet deployment schemeis proposed, which deploys mix of Macro-eNB, Micro-eNB and relay station (RS) by considering capacity, coverage andcost factors. The proposed scheme identifies the required number of eNBs, their types and deployment locations tooffer the expected coverage in a cost-effective way. The simulation results demonstrate that our proposed scheme is moreflexible and offers improved performance in terms of system cost and power ratio than the conventional HetNet deploymentschemes. © 2016, King Fahd University of Petroleum &amp; Minerals.
